>>>In the above but also in the blue / black plot - bomber shape diagram- the Elise is relatively good in the half past 10 h region = accelerations ( lateral and increasing speed ) measured in a fast left hand corner. The reason may be its fundamentally different mass distribution . Or do you have a better explanation Stan ? <<<
Well there are several things going on.
* On the half past 10 thing..this shows what you can do if you get some weight transfer onto the front tires. For about a 1/4 to 1/2 second you can get quite a bit more grip than steady state. Tires can briefly do higher cornering grip than they can maintain around a skid pad lap after lap. I tracked down those aspects of the chart. When I put the mouse pointer in those spots the program highlights where on the course the car was at the time.
* Street car versus CSP car
* Good driver versus great drivers
* Stock sized street tires, although sticky ones VS Huge Autocross Hoosiers.
* Elise accel and braking change things compared to a Miata momentum car. The Miata was later able to be floored from the hairpin all the way back to the finish - no lifting at all.
>>>Here all accelerarion values are smaller that in the blue / black plot . Was ist raining ? <<<<
Different runs, different things tried out. That run also had some of the starting line action removed if I recall correctly. Also, sometimes Miata guys use the clutch as a torque converter coming out of turns to help out a bit. No rain, good condtions all day, sunny, clear about 60 F.
